The effect of the replacement of corn silage with spineless cactus associated with Tifton 85 hay or sugarcane bagasse was evaluated on the performance, body weight components and sheep meat quality. Twenty-one Santa Inês male sheep with initial body weight of 22.9 ± 2.9 kg were used. They were confined in individual stalls for 74 days receiving the following diets: corn silage + concentrate (CS); spineless cactus + Tifton 85 hay + concentrate (TH); spineless cactus + sugarcane bagasse + concentrate (SB). After the feedlot period, the animals were slaughtered and their body components were weighed and sampled. Data were submitted to Tukey's test at 5% probability. The average daily gain (0.25 vs 0.14 kg), cold carcass weight (13.3 vs 13.7 kg), loin muscularity (0.6 vs 0.4 kg) and liver weight (0.7 vs. 0.5 kg) were higher (P < 0.05) for the TH diet when compared to that for the CS. The physical-chemical parameters of meat were not influenced (P > 0.05) by the treatments and presented about 20.1% of crude protein, 6.1% of crude fat and shear force of 2.0 kgf/cm. In complete diets for sheep, Tifton 85 hay associated with spineless cactus provides greater weight gain, cold carcass muscularity and organ weight when compared to those for animals fed with corn silage as exclusive roughage. Sugarcane bagasse associated with spineless cactus may replace corn silage in complete diets for sheep.
Objetivou-se com esse estudo avaliar o efeito de níveis crescentes de inclusão da raspa da mandioca em rações de codornas japonesas, na fase de postura, sobre desempenho, qualidade dos ovos e viabilidade econômica das dietas. Foram utilizadas 200 codornas fêmeas (Coturnix japonica) distribuídas em 25 gaiolas. Cinco dietas experimentais foram formuladas com níveis crescentes (0, 6, 12, 18 e 24%) de inclusão de raspa da mandioca na matéria seca da ração. Foram realizadas coletas para analise das características de qualidade dos ovos e desempenho das aves. A inclusão da raspa de mandioca na dieta proporcionou comportamento quadrático (P < 0,05) para o consumo de ração e conversão alimentar por dúzia de ovos. A percentagem de postura foi de 93,55% e não foi influenciada (P > 0,05) pelos níveis de raspa. A inclusão da raspa de mandioca não influenciou (P > 0,05) na percentagem do albúmen, percentagem de gema, percentagem de casca nem na cor da gema. A inclusão de 24% de raspa de mandioca proporcionou menores custos com arraçoamento. Recomenda-se a inclusão de até 12% de raspa de mandioca na ração de codornas em postura. Níveis mais elevadas (18 e 24%) promovem aumento do consumo de ração, piora na conversão alimentar e redução do peso do ovo.
RESUMO:Milhares de pessoas utilizam a carroça tracionada por equídeos como meio de trabalho ou suplementação de renda no âmbito mundial. Poucas são as pesquisas envolvendo a caracterização biométrica dos animais e as medidas dos equipamentos de atrelagem, buscando classificar os equídeos pela capacidade de tração, propondo discussões cientificamente embasadas acerca da capacidade de carga por animal, consequentemente diminuindo os maus tratos e dimensionando o trabalho de forma proporcional e coerente. Objetivou-se determinar parâmetros zoométricos ligados a ezoognósia, caracterizando tipologia e medidas relacionadas à veículos de atrelagem de 234 equídeos de tração no município de Arapiraca-Alagoas, Brasil. Foram obtidas medidas morfoestruturais lineares e perimetrais, calculando-se os índices zoométricos: índice corporal, peso estimado, índice dáctilo-torácico, índice de carga a passo e índice de carga a galope. Os dados foram submetidos a uma análise de variância e teste de médias (Skott-Knott a 5% de probabilidade). Os muares representaram 76% (179) dos animais estudados, os equinos 21% (49) e os asininos 3% (6). Em todas as medidas morfoestruturais e índices zoométricos, com exceção do índice corporal onde os asininos apresentaram a maior média, verifica-se diferença (P<0,05) entre as espécies com os equinos sempre apresentando maiores valores, seguidos pelos muares e asininos. Não há adequação em relação às medidas das atrelagens, verificando-se diferença estatística (P<0,05) apenas para os veículos tracionados por asininos. Os equinos e muares utilizados por condutores de carroças são classificados como equídeos de pequeno porte, com propensão à tração leve. Palavras-chave: carroça; equídeos urbanos; índices; medidas BIOMETRIC STANDARD, WAGON MEASURES AND LOAD INDEX OF URBAN CART EQUIDS OF ARAPIRACA CITY, ALAGOASABSTRACT: Thousands of people use the cart pulled by horses as a means of work or supplemental income in the world. But there are few studies involving the animal biometric characterization and wagon measures, seeking classify equids for traction capacity and propose scientifically sound discussions about the load capacity per animal, thus reducing maltreatment. The aim of this paper was to determine the zoometric standard, typology and wagon measures of the 234 cart equids from Arapiraca city, Alagoas state, Brazil. Morphostructural linear and perimeter measurements were obtained, calculating the zoometric indexes: body index, estimated weight, dactyl-thoracic index, work walking index and work galloping index. The variables were subjected to analysis of variance and means test (Skott-Knott 5% probability). The mules represented 76% (179) of the animals, horses 21% (49) and donkeys 3% (6). In all measurements and indexes studied, except where the donkeys body index had the highest average, there is a statistical difference (P <0.05) between species with the highest values always with horses, mules and followed by donkeys. There are no adequate in relation to the wagon measures, verifying differen...
This study evaluated the effect of replacing corn silage with spineless cactus, in combination with Tifton 85 hay or sugarcane bagasse, on the carcass measurements and sensory properties of the meat of lambs finished in feedlot. Twenty-one, intact, Santa Inês males, with an initial body weight of 22.86 ± 2.87 kg and an average age of 150 days, were individually confined for 74 days and fed at will three treatments diets: Corn silage (CS); Spineless cactus + Tifton 85 hay (CT) and Spineless cactus + sugarcane bagasse (CB). Lambs fed CT had a wider croup (p < 0.05) compared to animals fed CS. The replacement of corn silage with CT or CB did not influence (p > 0.05) the body length, withers height or chest circumference of the lambs. Values of carcass length and compactness index were similar (p > 0.05) between treatments. There was a high and positive correlation (p < 0.05) between chest width (0.82) and chest circumference (0.81) of animals with cold carcass weight. The odor and taste of sheep meat fed CT or CB was more accepted when compared to the meat of animals fed corn silage. The replacement of corn silage with spineless cactus in combination with Tifton 85 hay or sugarcane bagasse improves the sensory quality of sheep meat, but does not interfere with carcass measurements.
